You figured wrong. The correct format should be JH4NA126?NT001057.
You need to know the check digit before anyone can run the Carfax. You can figure out the check digit yourself. Just go to the NSX FAQ, click on General Info, then on Vehicle Identification Number. It tells you exactly how to calculate it. Figure it out, then ask for a Carfax of the entire VIN, and I'm sure someone will be happy to help you.
